NON-REFILLABLE BOTTLE SPECIFICATION forming part of Letters Patent No. 638,636, dated December 5, 1899.

Application filed November 5, 1897. Serial No. 657,584. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS HOGAN, of Toronto, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

My invention, which will be hereinafter fully set forth and claimed, relates to devices for preventing bottles from being refilled.

The object of my invention is a bottle that cannot be refilled.

Figure 1 is a vertical section through the center of my improved bottle, showing the same as filled and stoppered. Fig. 2 is a partial vertical section of the neck and stopper, taken at a right angle to Fig. l and showing the stopper-locking device. Fig. 3 is a top view of the stoppered mouth of the same. Fig. 4 is a horizontal section of the same on line 4 4, Fig. 1. Figs. 5, 6, 7, and 8 are horizontal sections of the same on lines 5, 6, 7, and 8, respectively, of Fig. 1.

My improved non-refillable bottle consists of two main parts, the bottle proper, A, and the stopper B, and the latter again is composed of several separate parts.

The bottle A has in the interior of its neck, some distance from the mouth, a downwardlyfacing annular shoulder a, Figs. 1 and 2, serving as an abutment for projecting stops in the stopper. A vent is provided in the bottom a. This consists of a passage 2 angular in direction, (and which may be double, as shown in Fig. 1,) having its outer orifice or orifices out of the center and diverging to a small central passage 3, opening into a conoidal chamber 4: and ending in a central tubular passage 4. The chamber 4 is a valvechamber with a true bottom a and true top a, as valve-seats, in a raised part A and containing a valve 0. From the upper conical valve-seat ct passages 5 diverge downwardly and outwardly through the raised portion A, Figs. 1 and 8, communicating with the interior of the bottle. The bottom of the valve 0 is the valve-face adapted to making a tight joint with the bottom of the chamber or. valve-seat a and closing the passage 3 when down, and the top, being conical, is the valve-face for the conical seat a, adapted to close the passages 5 when raised. The valve O conforms in shape to the'u-pper portion ct of the chamber 4, but has at the top a recess or indentation 0, adapted to receive the end of a wire to limit its traverse.

The sto er consists of a plug D, of hard or non-elastic material, either cylindrical or conical, filling the neck of the bottle with an easy fit and reaching below the shoulder a. its upper end projects outwardly and downwardly, forming an overhanging lip d and an annular groove 6, the bottom orlower edge of which lip is approximately level with the top of the bottle, (presuming the latter to be flat,) as shown. A groove 7 is preferably formed in the outer edge of the mouth of the bottle, adapted to receive the lower edge of the lip (Z of the stopper. In the groove 6 is placed an elastic packing-ring D, adapted to make a tight joint between the bottle-mouth and the stopper, the latter being not necessarily tight in the neck of the bottle.

In the upper end of the plug D is a central passage 8, Figs. 1 and 3, extending some dis tance down and terminating in a wide but shallow chamber 9. Around the outer margin of the bottom of said chamber are formed a series of small passages 10, Figs. 1, 4, and 5, extending downward and terminating in the sides of a valve-chamber 11, Fig. 1, having the form of a truncated conoid. This chamber has a recess or cavity 12, Figs. 1 and 5, of about the same diameter as the passage 8, extending upward a short distance, but not into the chamber 9. The bottom of said chamber forms a valve-seat c1 and has a downward central passage 13, terminating a little lower down in another laterally extended shallow valve-chamber 14, in which the top forms a valve-seat d. The bottom of this chamber 14 has a wide-mouthed conical recess 15, Figs. 1 and 6, terminating in a downward passage 16 coextensive with the plug D. At the outer margin of the bottom of the chamber 14 are a series of passages 17 extending downward coextensive with the:

plu The entire margin of the chamber 14' is, however, not perforated by passages 17 but two opposite spaces, one on each side, are spared out to afford room on each side for a recess 18, Figs. 2 and 7, just below the shoulder a, having its bottom sloping slightly inward and downward. Each recess is adapted to contain, loosely and flush with the outer surface, a small block D", which has its bottom beveled downward and inward, the bevel being more acute than that of the bottom of the recess. Thus when said block stands free in its recess it is bound to incline outwardly and project its upper end out of the recess, as shown in Fig. 2, the upper end just passing under the shoulder a, and thus forming an interlocking stop against said shoulder and preventing the withdrawal of the stopper from the neck of the bottle.

The valve-chamber 11 contains a valve D its .face 61" downward, normally resting on the bottom or valve-seat d" and its upper part or stem projecting into the recess 12 and being allowed a suitable rise therein if the bottle is inverted, so as to allow the valve to leave its seat.

The valve-chamber let 15 contains a valve D which normally rests in the recess 15 with its face (1 upward, separated from the top of the chamber or valve-seat Cl, and its stem extending into the passage 16. Said stem is provided with a non-corrosive wire (1 extending down through the passage 4 into the chamber 4 and in the recess (2 of the valve 0, not reaching, however, to the bottom of said recess, but leaving a space between the end of the wire and said bottom, so as toallow the valve 0 to rise from the lower seat without necessarily seating in the upper seat. On said wired is secured a float dplaced a little distance below the lower end of the plug D. The wire 01 is preferably made in two lengths for convenience in manufacture and for adjustment, the joint being within the float 61- The operation of the device is as follows: The bottle is filled and the stopper is inserted with the Wire 01 and float d, the wire being passed into the passage 4: and recess 0. During the insertion of the stopper the stops D are held in place by the inner face of the neck of the bottle. When the stopper is pushed down far enough to compress the clastic ring D rather more than is desired for a final compression, the upper end of the stops D pass the shoulder a, and their outward support being thus removed they fall outward under said shoulder and form an abutment between the bottle-neck and stopper and the latter cannot be withdrawn.

In emptying the bottle the latteris reversed and the float d rises in the liquid with which the bottle is filled and lifts or keeps the valve D from its seat (Z in the chamber lat, thus allowing the liquid to pass through the passage 17 into the valve-chamber 14 andthence into the passage 13. As the bottle is reversed the valve D drops by its own Weight from its seat and allows the liquid to pass into the chamber 11 and thence by the passage 10 into the chamber 9 and issue from the passage 8, which forms the mouth of the stopper. While the bottle is emptying, held reversed, the valve 0 in the vent drops from its seat a" and is held up by the wire (i which latter prevents it from dropping on its conical seat a'. The passages 2, 3, 4, and 5 are thus open and free for communication with the interior of the bottle, and air passes through the same to fill the void of the liquid escaping by the mouth of the bottle. When all the liquid has escaped and the bottle is empty, the float d is nolongerbeing supported and thereforedrops, and with it the wire 61 and valve D the latter closing the passage 13 and the end of the wire d allowing the valve 0 to drop into its upper (lower when bottle is reversed) seat a' and close up the passage 5. The vent is thus closed also and becomes uselessas a meansfor refilling. A cork may be inserted in the mouth of the passage 8 for convenience in carrying the bottle upside down when filled.

hen the bottle is empty and held upright, the valve 1) is open, but the valve D is closed, and any liquid poured in fromthe top through the passages S, 9, and 10 could -not pass farther than the chamber 11 and could not enter the passage 13.
